Power Restore
When a utility power failure occurs, PowerPanel
®
Business Edition software may order the computer to shut down and
power off after the specified remaining runtime is met or if the battery capacity is low. After the utility power is restored
the UPS turns on automatically and supplies power to the computer. If the computer BIOS is set to boot when power
is restored the computer will automatically restart.
The following settings are used to configure the UPS restore behavior:
 Automatic Restore: When this option is enabled, the UPS will restore output immediately when the utility power
is restored. When this option is disabled, the UPS will not restore output at that moment and users have to turn it
on manually.
 Mandatory Power Cycle: When a shutdown sequence is initiated due to a power failure, the connected
computers may be ordered to shut down and the UPS will be also ordered to turn off after a time delay. If the utility
power is restored prior to the UPS shutting off, the UPS will still turn itself off. In this circumstance, the utility power
has restored, but the connected computers have shut down and the UPS has turned off.
If the Mandatory Power Cycle option is enabled, the UPS will also turn off after a time delay, but it will turn on
again about 10 seconds later. The UPS has restarted and then all connected computers will boot.
Note: Most computers have the ability to boot when utility power is restored. Make sure this function is supported
and enabled in the system BIOS.
 Recharged Delay: When the utility power is restored, the UPS will start to recharge until the specified delay is
expired before restoring output power.
 Recharged Capacity: When the utility power is restored, the UPS will start to recharge until the specified battery
capacity is met before restoring output power.
 Startup Delay: When the utility power is restored, the UPS will delay the restoration of output power. This option
can be used to stagger the startup time of multiple UPS to avoid overloading the utility power circuit or power
source. The Startup Delay option will take effect every time when the UPS is about to restore power. This also
includes the scheduling task.
 Stable Utility Delay: When the utility power is restored, the UPS will delay switching to normal operation from
using battery power. If the battery capacity is lower than the Low Battery Threshold as power is restored, the UPS
will switch to normal operation immediately. This option can be used to prevent frequent outage due to unstable
utility power.
 Restore Action: Sets the operating mode after utility power restores. If the Bypass option is selected, the UPS
will enter to bypass mode and supply power from the bypass module to connected equipment when utility power
restores. If the Online option is selected, the UPS will supply power from the UPS modules to connected
equipment when utility power restores. If the Standby option is selected, the UPS will be off when utility power
restores.
